Pebble, the E-Ink smart-watch for iPhones and Android devices which raised over 10 million dollars on Kickstarter is about to get a lot of new features. Today, Pebble announced that the watch SDK is being released today. The SDK will allow developers to create custom watch faces, alerts and new apps.

At the moment, there’s less than 10 available watch faces and only one app, but expect those numbers to grow dramatically now that developers can get their hands on a public SDK.
